| EXTRACT FROM "POPULAR MECHANICS" (U.S.A.) - JULY 1929. CHEMICAL FOR COOLING MOTORS TO AID AVIATION. Air-corps engineers, at Wilbur Wright field, have developed a chemical to replace water for cooling airplane motors. Fewer gallons are required, making a reduction of more than eighty pounds in weight; a radiator one-fourth the size of the present type can be employed, thereby also decreasing wind resistance, and higher speeds can be developed safely because the liquid absorbs heat to a higher degree than water and there is, consequently, less danger of overheating. The chemical is expected to greatly enlarge the field for the present type of engine. Only mior changed are required to make the motors suitable for using the substance. Planes will be able to increase their payloads without a corresponding expense due to the reduction in the weight of the radiator and liquid carried, and higher speeds with consequently faster and more attractive schedules can be maintained. Army engineers, who have been testing the liquid for some time, report that the speed of a standard pursuit plane was increased eleven miles an hour by using the chemical since the weight was reduced. It boils at 387 degrees Fahrenheit, 175 degrees above the boiling point of water. | ||
